In fact, data suggests that about 20 percent to 40 percent of sudden cardiac deaths are precipitated by acute emotional stressors, and cardiac dysfunction that’s triggered by emotional stress can increase the risk of arrhythmias. Prolonged activation can elicit the release of adrenaline from the adrenal medulla. Sympathetic nervous system stimulation causes vasoconstriction of most blood vessels, including many of those in the skin, the digestive tract, and the kidneys. When the sympathetic nervous system is active, it causes the bladder to increase its capacity without increasing detrusor resting pressure (accommodation) and stimulates the internal urinary sphincter to remain tightly closed. The sympathetic and parasympathetic nervous systems are important for modulating many vital functions, including respiration and cardiac contractility. It is a network of interconnected neurons that prepares the body to deal with the conditions of stress and fear. Which is an exclusively sympathetic function. The pattern of anihidrosis may help identify the lesion. The sympathetic system is a division of the somatic system, while the parasympathetic system falls under the autonomic system. For example, the sympathetic nervous system can accelerate heart rate; widen bronchial passages; decrease motility (movement) of the large intestine; constrict blood vessels; increase peristalsis in the oesophagus; cause pupillary dilation, piloerection (goose bumps) and perspiration ; and raise blood pressure. The sympathetic division typically functions in actions requiring quick responses. It basically undoes the work of sympathetic division after a stressful situation.
